Improving adhesion, barrier performance, anti-static properties, and product protection in rigid plastic packaging

Rigid plastic bottles and containers are lightweight and cost-efficient, but their surface properties can limit adhesion, coating, or barrier performance. Oxygen ingress, poor printing quality, and migration risks can compromise product safety and shelf life.

Delta Engineering develops fully automated surface treatment and coating systems that enhance barrier strength, adhesion, and hygiene. Our fully automated systems integrate seamlessly into the customer’s production line, delivering consistent, food-safe, and sustainable surface modifications for every rigid plastic package.

Plasma coating

Delta Engineering’s plasma coating applies an ultra-thin barrier inside plastic bottles and containers. It prevents oxygen ingress, protects product aroma, and extends shelf life, all while maintaining full recyclability.

Spray coating

Our spray coating systems apply a glossy, anti-static, and scratch-resistant layer to PET bottles. Designed to improve handling on filling lines and enhance the appearance of high-quality products, they ensure optimal coverage, precise solvent control, and consistent performance, even at high speeds.

Plasma treatment

Before printing or labeling, plasma treatment activates the plastic surface, improving wettability and adhesion. The result: durable print quality, reduced defects, and longer-lasting decoration without chemical primers.
